a flushing component with an anti-siphon function comprises a spray washing unit, wherein a three-way valve is arranged at the water inlet end of the spray washing unit, one channel of the three-way valve is connected with the water inlet end of the spray washing unit, the other channel of the three-way valve is connected with a water inlet joint, and the third channel of the three-way valve is connected with an anti-siphon joint; and a piston channel is arranged between the anti-siphon joint and the third channel of the three-way valve, and a piston capable of closing or opening the piston channel is arranged in the piston channel.

Preferably, the spray unit comprises a sleeve and a spray head which can be retracted into or extended out of the sleeve.

Preferably, said spray unit comprises two sleeves; the three-way valves are provided with two connecting seats which are formed in parallel; the water outlets of the two three-way valves are respectively connected with the water inlet ends of the two sleeves.

Preferably, the anti-siphon fitting is connected to the air vent end of the connecting socket, which comprises the air vent and the connecting socket.

Preferably, the piston channel has two, juxtaposed piston sleeves.

Preferably, there are two pistons, and the diameter of the upper half of each piston is smaller than the inner diameter of the piston channel, and the diameter of the lower half is larger than the inner diameter of the piston channel.

Compared with the background technology, the technical scheme has the following advantages:

the utility model is provided with a three-way valve at the water inlet end of the spray washing unit, one channel of the three-way valve is connected with the water inlet end of the spray washing unit, the other channel is connected with a water inlet joint, and the third channel is connected with an anti-siphon joint; and a piston channel is arranged between the anti-siphon joint and the third channel of the three-way valve, and a piston capable of closing or opening the piston channel is arranged in the piston channel. When siphonage takes place, the piston moves under the suction effect, opens the piston passageway, and inside gas entering prevented siphonage from taking place to prevent that the filth from getting into inside the spray rinsing subassembly.

Detailed Description

Referring to fig. 1 and 2, a washing assembly with an anti-siphon function includes a spray head 1, a sleeve 2, an anti-siphon joint 3, a piston sleeve 4, a piston 5, a first water inlet joint 6, a connecting seat 7, a second water inlet joint 8, and the like.

The spray head 1 and the sleeve 2 constitute a spray unit. In this embodiment, there are two spray heads, a first spray head 1-1 and a second spray head 1-2, respectively, and correspondingly, there are two sleeves 2, a first sleeve 2-1 and a second sleeve 2-2, respectively, and the two spray heads can be retracted into the two sleeves or extended out of the sleeves, respectively. The telescopic structure is prior art. The two sleeves are secured together side-by-side.

In other embodiments, a single spray head and a single sleeve may be used in combination.

In other embodiments, the spray unit may also be constructed in other ways, for example, folded.

The sheathed tube end of intaking is fixed to be equipped with connecting seat 7, refers to fig. 4 to 6, and connecting seat 7 includes two linkage units that set up side by side, and every linkage unit is three-way valve structure respectively, including water inlet, delivery port and blow vent. Wherein, the water inlet of the left connecting unit is a first water inlet 7-4, and the air vent is 7-2; the water inlet of the right connecting unit is a second water inlet 7-5, the air vent is 7-3, and the water outlets 7-1 of the two connecting units are respectively connected with the water inlet ends of the two sleeves. The first water inlet 7-4 is connected with the first water inlet joint 6, and the second water inlet 7-5 is connected with the second water inlet joint 8.

Referring to fig. 7, the anti-siphon connector 3 is connected to the air vent end of the connection seat 7, and includes an air vent pipe 3-1 and a connection seat 3-2. Referring to fig. 8, the piston sleeve 4 includes two piston channels 4-1 in parallel. In assembly, the two piston channels are provided in the vent openings 7-2 of the two connection units, respectively. The number of the pistons 5 is two, the diameter of the upper half part 5-2 of each piston is smaller than the inner diameter of the piston channel 4-1, and the diameter of the lower half part 5-1 is larger than the inner diameter of the piston channel 4-1. The upper half 5-2 is inserted into the piston channel 4-1 when being installed.

The utility model discloses an use as follows:

referring to fig. 6, in the spray washing, water flows in from the water inlet 7-4 or 7-5 and then enters the casing 2 from the water outlet 7-1. In the process, the piston 5 is pushed upwards, and the lower half part of the piston closes the piston channel 4-1, so that water flow cannot enter the anti-siphon joint 3; when the siphon phenomenon occurs, the piston 5 moves downwards, the piston does not close the piston channel 4-1 any more, and gas enters the water channel from the anti-siphon joint 3 to block the siphon and prevent liquid from flowing backwards.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
